Browser Automation Skill

Web browser automation using agent-browser with AI-optimized snapshots. Reduces context by 93% using element refs (@e1, @e2) instead of full DOM.

Core Workflow

# 1. Navigate to page
agent-browser open <url>

# 2. Get accessibility tree with element refs
agent-browser snapshot -i    # -i = interactive elements only

# 3. Interact using refs from snapshot
agent-browser click @e2
agent-browser fill @e3 "text"

# 4. Re-snapshot after page changes
agent-browser snapshot -i

Quick Reference

Navigation

Command	Description
`open <url>`	Navigate to URL
`back`	Go back
`forward`	Go forward
`reload`	Reload page
`close`	Close browser

Snapshots (AI-Optimized)

Command	Description
`snapshot`	Full accessibility tree
`snapshot -i`	Interactive elements only (buttons, links, inputs)
`snapshot -c`	Compact (remove empty elements)
`snapshot -d 3`	Limit depth to 3 levels
`screenshot [path]`	Capture screenshot (base64 if no path)

Interaction

Command	Description
`click <sel>`	Click element
`fill <sel> <text>`	Clear and fill input
`type <sel> <text>`	Type with key events
`press <key>`	Press key (Enter, Tab, etc.)
`hover <sel>`	Hover element
`select <sel> <val>`	Select dropdown option
`check/uncheck <sel>`	Toggle checkbox
`scroll <dir> [px]`	Scroll page

Get Info

Command	Description
`get text <sel>`	Get text content
`get html <sel>`	Get innerHTML
`get value <sel>`	Get input value
`get attr <sel> <attr>`	Get attribute
`get title`	Get page title
`get url`	Get current URL

Wait

Command	Description
`wait <selector>`	Wait for element
`wait <ms>`	Wait milliseconds
`wait --text "text"`	Wait for text
`wait --url "pattern"`	Wait for URL
`wait --load networkidle`	Wait for load state

Sessions

Command	Description
`--session <name>`	Use isolated session
`session list`	List active sessions

Selectors

Element Refs (Recommended)

# Get refs from snapshot
agent-browser snapshot -i
# Output: button "Submit" [ref=e2]

# Use ref to interact
agent-browser click @e2

CSS Selectors

agent-browser click "#submit"
agent-browser fill ".email-input" "test@test.com"

Semantic Locators

agent-browser find role button click --name "Submit"
agent-browser find label "Email" fill "test@test.com"
agent-browser find testid "login-btn" click

Examples

Login Flow

agent-browser open https://example.com/login
agent-browser snapshot -i
agent-browser fill @e2 "user@example.com"
agent-browser fill @e3 "password123"
agent-browser click @e4
agent-browser wait --url "**/dashboard"

Form Submission

agent-browser open https://example.com/contact
agent-browser snapshot -i
agent-browser fill @e1 "John Doe"
agent-browser fill @e2 "john@example.com"
agent-browser fill @e3 "Hello, this is my message"
agent-browser click @e4
agent-browser wait --text "Thank you"

Data Extraction

agent-browser open https://example.com/products
agent-browser snapshot -i
# Iterate through product refs
agent-browser get text @e1  # Product name
agent-browser get text @e2  # Price
agent-browser get attr @e3 href  # Link

Multi-Session (Swarm)

# Session 1: Navigator
agent-browser --session nav open https://example.com
agent-browser --session nav state save auth.json

# Session 2: Scraper (uses same auth)
agent-browser --session scrape state load auth.json
agent-browser --session scrape open https://example.com/data
agent-browser --session scrape snapshot -i

Integration with Claude Flow

MCP Tools

All browser operations are available as MCP tools with browser/ prefix:

browser/open
browser/snapshot
browser/click
browser/fill
browser/screenshot
etc.

Memory Integration

# Store successful patterns
npx @claude-flow/cli memory store --namespace browser-patterns --key "login-flow" --value "snapshot->fill->click->wait"

# Retrieve before similar task
npx @claude-flow/cli memory search --query "login automation"

Hooks

# Pre-browse hook (get context)
npx @claude-flow/cli hooks pre-edit --file "browser-task.ts"

# Post-browse hook (record success)
npx @claude-flow/cli hooks post-task --task-id "browse-1" --success true

Tips

Always use snapshots - They're optimized for AI with refs
Prefer -i flag - Gets only interactive elements, smaller output
Use refs, not selectors - More reliable, deterministic
Re-snapshot after navigation - Page state changes
Use sessions for parallel work - Each session is isolated
